METAL WEATHER STRIP.

Application filed February 16, 1922. Serial No. 536,923.

To all 'whom t may concern Be it lrnown that we, LUTHER C. Ynrcn and ROBERT H. G. PARKER, citizens of the United lStates, residing at Reading, in the c county of Berks and State of Pennsylvania,

have invented certain new and useful Improvements in Metal Weather Strips, of which the following is a specification.

This invention relates to improvements in metal weather strips, and it is intended more particularly for use in connection with metal window frames and sash.

The object in the present invention is to provide means for weather stripping metal Windows of the usual construction, capable of being applied thereto after the windo-ws have been placed in position, as differentiating from a window frame and sash especially constructed with weather proofing 2@ means.

Our invention comprises a resilient metal weather strip in connection with a suitable weather strip retaining member, which member may be applied to the window frames of various forms either when manufactured or after they have been placed in the building.

The invention is more fully described in the following specification and clearly illustra-ted in the accompanying drawing, in which Fig. l is a sectional view taken through a window frame and sash, showing the invention applied thereto.

Fig. 2 is a fragmentary detail view of a portion of the retaining member.

Fig. 3 is a like view of the weather strip.

The numeral 1 designates a window frame of substantially angular form and simple construction.

The numeral 2 designates a portion of the sash, which, as in all cases of this character, is pivotally mounted in the usual manner in the frame and adapted to swing to open or closed position therein.

Interposed between the meeting edge of the swinging member, 3, and the surface of the window frame 4, we place a metal retaining member 5, secured to the Jframe by.

means of rivets 6. This retaining member is formed with a longitudinal groove 7 formed by bending the one edge of the member back on itself, and within this groove the metal weather strip is placed and it is held therein by frictional engagement alone.

The numeral l0 designates the weather strip, which we prefer to make of resilient brass, and this strip is formed with a right angled longitudinal edge 11 adapted to enter and be held in the groove 7 of the retaining member.

The free end of the strip, designated by the numeral 13, projects from the bent portion in a curve, and extends across that portion of the frame at which the sash would meet it.

When the sash is closed, the edge of the sash, 3, will contact with this curved resilient portion of the strip, and depress it, insuring a substantially closed joint as between the sash and the frame.

This resilient member is of such dimensions and resiliency that any unevenness therein will be taken up when the sash is closed, and this meeting of the edge of thev sash and the resilient strip constitutes the only meeting point as between the sash and the frame, thus eliminating any danger of the two meeting surfaces not contacting pro erly.

aving thus described our invention, what we claim and desire to secure by Letters Patent is l. In a metal weather strip for windows, a l metal retaining member having a flat body portion and one longitudinal edge bent at right angles thereto and forming an open groove, in combination with a weather strip of light, resilient metal having o-ne longitudinal edge bent at right angles to its body and adapted for frictional engagement in said groove while the other edge is curved to bring it free from contact with the window frame.

2. In a one-point contact weather strip for windows, a weather strip retainer adapted for attachment to the window frame, said retainer comprising a flat body portion substantially U-shaped groove, and a resilient metal 'Weather strip, one longitudinal l edge of which s bent at an angle to the body thereof and adapted to fretionally engage the said groove While the opposite 1ongitudinal edge is curved to hold it free' from Contact withy the Window fra-me and to provide the single point of Contact fory the sash When closed. y v 10 In testimony whereof We affix our signatures. 1 l
